Summary: Exploring efficient photocatalysts for degrading hazardous volatile organic compounds (VOCs) is gaining popularity. By incorporating Co dopant into the WO3 lattice, Co-doped WO3 nanofibrous photocatalysts were developed, leading to significant charge rearrangement and localized electric field. This enhanced oxygen adsorption and activation, driving photoexcited electrons to gather at the Co dopant and achieving spatial charge separation. The improved photocatalytic oxidation of gaseous HCHO and CH3COCH3 by Co0.8-WO3 nanofibers highlights the importance of dopant-induced oxygen adsorption and LEF-induced efficient carrier separation. These findings offer a new direction for developing more efficient photocatalysts using unique doping approaches.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
